Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a tank made of a synthetic resin (hereinafter, referred to as a resin tank) for storing cleaning water supplied to the toilet body side.
The present invention relates to a structure for attaching to a toilet body of a pottery product having variations in dimensional accuracy without being deformed.

[Conventional technology]

If an example of a toilet bowl using a conventional resin tank is shown,
This is as shown in FIGS. This kind of resin tank 1
Is mounted on the rear side of the toilet body 2 with the packing 3 interposed therebetween, and the tight-fitting bolt 4 inserted from the inside of the resin tank 1
The nut 5 is attached by screwing. And
A pottery cover 6 is attached around the resin tank 1 so as to provide a sense of unity with the pottery body 2. A valve seat 9 of a float valve 8 is attached to the bottom of the resin tank 1 via a packing 7.

To clean the toilet bowl, rotate the operating handle 10
The valve seat 9 pulls up the float valve 8 via 11. As a result, the cleaning water in the resin tank 1 flows out into the drainage passage 12 on the toilet body side to carry out the waste in the toilet bowl and clean the inside of the toilet bowl. When the water level of flush water drops, the float valve 8 comes to sit on the valve seat 9, and the supply of flush water to the toilet body side is stopped. On the other hand, the floating balls 13 are also lowered as the water level of the washing water is lowered, and the washing water is supplied from the ball tap 14. Then, after the float valve 8 is closed, when the water level of the wash water is restored to the original state, the floating ball 13 is moved to the ball tap 14
Is closed to complete a series of cleaning operations. This is a normal cleaning operation.

In addition, as another mounting method of the conventional resin tank 1,
Some are shown in FIG. 6 and FIG. In this conventional example, a mechanical box 15 for installing equipment such as a cleaning nozzle of a local cleaning device, a hot water tank, and a warm air device is formed on the rear side of the toilet body 2. An opening 16 is formed on the upper surface side of the mechanical box 15. The resin tank 1 is mounted by mounting and fixing the base plate 17 on the opening 16 and mounting the resin tank 1 on the base plate 17. Then, the tight-bonding bolt 4 is arranged from the inside of the resin tank 1 through the base plate 17 and a part of the toilet body 2, and is fastened by the nut 5. In this case, a packing 18 is provided on the tightly-bonding bolt 4 on the inner side of the resin tank 1, and a tightly-fitting packing 19 is provided between the resin tank 1 and the drainage passage 12 of the toilet body 2. ing. The other mounting structure of the float valve 8 and the toilet cleaning operation are the same as those of the conventional example shown in FIGS. 3 and 4.

[Problems to be solved by the device]

By the way, in the conventional structure for mounting the resin tank 1 on the toilet bowl, in any case, the tight-fitting bolt 4
Is inserted into a part of the toilet body 2 from the inside of the resin tank 1 and is fastened with a nut 5. Then, the resin tank 1 is leaked through the packings 3 and 18. Therefore, the fastening with the tightly-bonded bolts 4 and the nuts 5 needs to be performed firmly so that the packings 3 and 18 have a water-stopping function in addition to preventing the resin tank 1 from moving. .

However, if the tight connection between the tightly-bonded bolt 4 and the nut 5 is firmly performed, the bottom of the resin tank 1 may follow the shape of the toilet body 2 and may be deformed. This deformation is a pottery product in which the toilet body 2 is fired at a high temperature of around 1200 ° C., so the thermal expansion and contraction during firing are large,
This is because the planar shape of the portion of the toilet body 2 where the resin tank 1 is installed is not smooth.

When the resin tank 1 is deformed in this way, the packings 3 and 18 and the packings 7 and 19 of the float valve seat 9 are distorted in shape, and there is a drawback that the sealing performance of the parts is impaired. Further, the deformation of the resin tank 1 may result in an accident such as damage of the resin tank 1 itself.

Moreover, since the overflow pipe 9a is attached to the float valve seat 9, it is located in the center of the tank,
There was a risk of interfering with the movement of the floating ball 13 of the ball tap 14.
